AP PSYCHOLOGY

Detailed explanation-1: -Photoreceptors in the retina are classified into two groups, named after their physical morphologies. Rod cells are highly sensitive to light and function in nightvision, whereas cone cells are capable of detecting a wide spectrum of light photons and are responsible for colour vision.

Detailed explanation-2: -So, the cones are used for color vision and are better suited for detecting fine details. There are about 6 million cones in the human retina.

Detailed explanation-3: -Which colors humans and other animals see depends on the light-sensing cells, or photoreceptors, in the eye. There are 2 types of photoreceptors: rods, which detect dim light and are used for night vision, and cones, which detect different colors and require brightly lit environments.

Detailed explanation-4: -Cones = retinal receptor cells that are concentrated near the center of the retina and that function in daylight or in well-lit conditions. The cones detect fine detail and give rise to color sensations.

Detailed explanation-5: -The retina is covered with millions of light sensitive cells called rods and cones. When these cells detect light, they send signals to the brain. Cone cells help detect colors.
